+// First checked in on 98/11/20 by John R. McMullen in the wrong directory.
+// Checked in again 98/12/04.
+// Polished version 98/12/08.
+// Completely rewritten to integrate with nsIInputStream and nsIOutputStream (the
+// xpcom stream objects.
+
+//========================================================================================
+//
+// Classes defined:
+//
+// nsInputStream, nsOutputStream
+// These are the lightweight STATICALLY LINKED wrappers for
+// the xpcom objects nsIInputStream and nsIOutputstream.
+// Possible uses:
+// If you are implementing a function that accepts one of these xpcom
+// streams, just make one of these little jobbies on the stack, and
+// the handy << or >> notation can be yours.
+//
+// nsInputFileStream, nsOutputFileStream
+// These are the STATICALLY LINKED wrappers for the file-related
+// versions of the above.
+// nsIOFileStream
+// An input and output file stream attached to the same file.
+//
+// This suite provide the following services:
+//
+// 1. Encapsulates all platform-specific file details, so that file i/o
+// can be done correctly without any platform #ifdefs
+//
+// 2. Uses NSPR file services (NOT ansi file I/O), in order to get best
+// native performance. This performance difference is especially large on
+// macintosh.
+//
+// 3. Allows all the power of the ansi stream syntax.
+//
+// Basic example:
+//
+// nsFileSpec myPath("/Development/iotest.txt");
+//
+// nsOutputFileStream testStream(myPath);
+// testStream << "Hello World" << nsEndl;
+//
+// 4. Requires streams to be constructed using typesafe nsFileSpec specifier
+// (not the notorious and bug prone const char*), namely nsFileSpec. See
+// nsFileSpec.h for more details.
+//
+// 5. Fixes a bug that have been there for a long time, and
+// is inevitable if you use NSPR alone:
+//
+// The problem on platforms (Macintosh) in which a path does not fully
+// specify a file, because two volumes can have the same name.
+//
+// Not yet provided:
+//
+// Endian-awareness for reading and writing crossplatform binary files. At this
+// time there seems to be no demand for this.
